Me and my friend cant streetpass each other

for the past month the streetpass relay hasn’t been working for me, I have a few friends added in a group, they were all able to streetpass relay each other but none of them were able to streepass me and I specificaly have been unable to streetpass any of them. I’m using nimbus 1.6.0 and on system menu 11.16.0-49U. do i need to install the system menu update 11.17 for streetpass to work?
